x= -13 , y=11
Step-by-step explanation:
Using elimination method, make the x variable equal to eliminate the variable
-3x - y = -28
2x+ 3y=7
2(-3x-y =28)
3(2x+3y=7)
-6x - 2y =56
6x +9y=21
Apply addition
7y = 77
y=77/7 = 11
Use the value of y=11 in
2x+ 3y=7
2x +3(11) =7
2x +33 =7
2x=7-33
2x= -26
x= -26/2 = -13

Answer:
Each side is 2n - 5.
Step-by-step explanation:
The perimeter of an equilateral triangle is given by:
Where s is the length of each side.
The total perimeter is given by:
So, by substitution:
Then the length of each side is:
Each side measure 2n - 5.
